I am converting a small understairs room in a 30's Semi into a small bathroom (it used to be the "Coal Hole" in years gone by!).
The side walls are both brick, in reasonable condition, although there is some loose and powdery mortar. Both walls are damp - I can see small beads of moisture on the surface of the pointing. The brickwork has been painted with a thin coat of emulsion paint at some date long past. The paint adhesion to the brickwork seems pretty good.
I am planning to tile the walls, but it seems to me that I will need some kind of waterproofing before applying the tiles. Can anyone recommend a suitable product, preferably one that could be applied directly to the brickwork, as I am very tight for width in the room and cannot afford any solution that would add more than about 12mm to each wall?
Many thanks
